title: [A clinicopathological study of 10 cases of primary small bowel adenocarcinoma].
abstract: Between 1989 and 2009, 10 patients with small bowel adenocarcinoma were treated in our hospital. These tumors appeared in the jejunum in 6 patients and in the ileum in the remaining 4 patients. All patients had some symptoms. The median size of the tumors was 50mm(30-110mm). All tumors were advanced type 2 lesion with severe stricture. Histologically there were 8 well, 1 moderately and 1 poorly differentiated adenocarcinomas. There were 8 tumors invading the serosa and 2 tumors invaded other organs. Positive lymph nodes were identified in 6 cases. Liver metastasis and peritoneal dissemination were identified in 3 and 4 cases, respectively. Eight cases were diagnosed as small bowel adenocarcinoma preoperatively by double balloon endoscopy. The 4 patients with stage II tumor and 2 patients with stage III tumor underwent curative-intent surgery. The 4 patients with stage II tumor are all surviving without evidence of disease now.
